Bake 8 to 10 minutes until bottoms and edges are just brown. Cool on sheet on a wire rack 2 minutes before removing to rack to cool completely.

To ice and decorate: For each color, put a small portion Decorating Icing into a cup. Stir in food color. Leave remaining icing white.

Spoon some white icing into a ziptop bag. Cut tip off a corner; pipe outline on areas of snowman that will be white. To thin icing for coating: Add drops of water to white icing in bowl until thin enough to spread without dripping. Dip a brush into thinned white icing. Spread to piped border; sprinkle hands and feet with decorating sugar. Let dry 3 hours.

Scrape colored icing into ziptop bags; pipe around hats and scarves. Thin remaining colored icing; fill in. Pipe buttons and eyes and insert orange sprinkles as noses. Let dry at least 6 hours before storing in a single layer. Decorating Icing: In a large bowl, with mixer on low speed, beat 1 lb confectioners' sugar (3 1/4 cups) and 3 Tbsp Just Whites (powdered egg whites, see Note) until combined. Add 6 Tbsp water; beat until blended. Increase mixer speed to high and beat 8 minutes or until icing is very thick.
